T @ZZ whom t may concern.-

Be it known that I, JOHN L. Since, of the city of Chicago, in the countyof Cook and State of Illinois, have made an invention in theFloor-Frames of Cars, especially designed for use in tubular cars, ofwhich the following is a specification.

My invention consists, first, of a new and useful bracket so constructedand attached to 1o the longitudinal rods or piping of a tubular car asto receive and firmly attach thereto the ordinary car-sillsheretofore inuse,upon which the usual superstructure or housing of cars can be builtas heretofore constructed; secr 5 ondly, in a new and useful inside endcasting ofthe two forms herein shown and described, the primary officeof which is to receive the said longitudinal tubes or piping and toconnect same with the end sills of the car, but

2o which casting in one of the forms shown is also used as an insidecorner casting, through which bolts pass in two directions through theend and side sills to attach thereto the outside corner or push plate;thirdly, in peculiar means for attaching the end of said longitudinalrods or tubing to the end sills; fourth, in substituting channel-'irondrawtimbers77 of a peculiar construction, and attaehing the saine' by anew and useful means 3o to the end sill and to the transom, and havingattached to their inner faces peculiar checkplates, against which thefollowers of the draw-spring operate; and my inventionl further eonsistsin certain combinations of parts,

3 5 hereinafter in the claims set forth.

In the drawings, Figure l is a vertical section through the sill S andthe longitudinal tubes T and the sill-castingv S C, which constitutesthe first part of nly invention, and

4o showing in dotted lines the tie-rod running from a flange of saidcasting through the sill to the plate. I prefer to make the said flangeof this casting about three inches wide in the direction of the lengthof the sill, (I make it of the width of -the rest or body portion of'said casting) and niake in said iange two holes, in either of which theplate tie-rod may be inserted, according as it may be used as a right orleft casting. The head of the sill- 5o bolt s Z), (shown partially indotted lines,) which bolt fastens the sill to said bracket and whichbolts pass through the side and end 6o sills, respectively, to fastenthe outside cor ner or push plate, Fig. 2 being a front elevation fromthe inside of the floor-frame, and Fig. 3 being a vertical section ofthe said corner casting on a line corresponding to x x of Fig. 2. Boththese castings are made of just suiiicient height to iit between theupper and lower flanges of the end sill,when iianged sills are used, andare of any convenient Width.

In these figures, C C C C indicate partial cyl- ,7o inders or cups ofthe diameter of the outside periphery of the longitudinal tubes to be received therein, and, say, one and one half' inch deep. C, Fig. 2,indicates the hole in said casting through which the rod passes from thebolster to the end sill, which rod is hereinafter described'. C, Fig. 3,indicates the hole in said casting through which ashort bolt passesthrough the end sill to fasten one flange of the outside corner casting,and C" 8o a similar hole for a similar short bolt passing through theside sill to said outside corner Casting.

Fig. 4L is a vertical section through an end sill, A, through an insideend casting, B, and through longitudinal tubes T, showing the threadedplugs I? I), which are screwed into the end of the tubes, the inner endsof which plugs are cut out at their center in the form and depth of theangular heads ofthe bolts I) b, 9o

Ywhich pass through said plugs and through the inside end 'casting andthrough the end sill to fasten the tubes thereto. I prefer to make thisplug of malleable iron, and I cast on the inner end two or more bossesor knobs, d d, which are bent over the end of the head of the bolt afterthe latter is inserted, so as not to lose it in the tube after the `plugis screwed into place. Two nuts screwed onto the end bolts outside theend sill fasten the whole toroo gether.

I am aware that complicated arrangements consisting of a sleeve on theoutside ofthe end of the tube flanged inwardly to form a shoulder forthe head of the bolt have been heretofore designed for .this purpose,although, as far as I am aware, they have not been used or patented.

By the above means I provide a cheap, siniple, and reliable fasteningwhich is readily applied.

Fig. 5 shows my improved means of strapping and keeping in place thesaid tubes, and it consists in two castings and two elastic straps, (thelatter being made preferably of steeh) as clearly shown in said figure,which is an end elevation thereof, in which E E are two castingsfastened together at each end by two bolts (not shown) passing,respectively, through the upper and lower part of said casting, and alsothrough the two springstraps c c, which, rcspeetivel y, embrace the saidtubes. rlhe said castings E E may or may not be made to accommodate arod at c', and the parts E E may be cast in one piece. It is, however,more economical in construction and easier of application to east thesame in two parts, as shown. The hole at c is necessary in strapping theintermediate tubes between the end sill and the transom to accommodatethe supplemental rod of the draw-bar arrangement hereinafter described.

Figs. G and 7 illustrate my channel iron draw-beams, the latter being anend view thereof. In Fig. 6 holes 1 and 2 are for two bolts or rivetswhich secure an ordinary angleiron. (Notshown.) rlwo otherbolts orrivetsare fastened through the other part of this ordi nary angle-iron to theend sill. The other end of the angle-iron draw-beam is fastened to thetransom in a different and peculiar manner, soon to be described. Holes3, 4, 5, and 6 are for bolts or rivets which fasten the springcheck-plates to the angle-iron draw-beam. Holes 1l. 12, 13, and 14 arefor lugs which are cast upon said cheek-plates, and tit into and throughsaid last-named holes. The said lugs and lastanentioned holes may bedispensed with.

Fig. S shows one of said check-plates, the said lugs on the reverse sidebeing shown in dotted lines. For the other end of said channel-irondraw-beam I use a casting of the forni shown in Fig. 9, having fourholes, through which bolts or rivets pass to and through holes 7,8,9,and in Fig of the channel-iron drawbeam, and I pass in the otherdirect-ion through and through the bolster a strong T- headed bolt,having a screw-thread and nut on the end nearest to the channel-irondraw-beam. The casting shown in Fig. 9 can also be used for fasteningthe said channel-iron beam and the end sill together.

Fig. 10 of the drawings shows the paris herein described assembled in afloor-frame, with the wooden sills broken oft midway ot the length ofthe frame to better show the construction thereof, the same being, asshown in said figure, ready for the flooring and superstructure of thecar. Fig. 11 shows the draw-bar organism, and as well the lateralstrengthening-rods (not lettered) extending backward from the end sillparallel with the main tubing T. Fig. 12 shows one forni of thedevieeshown in Fig. 5 for strapping together and keeping in place thelongitudinal tubes, the form shown in Fig. 12 being intended for use atthe center of the floor-frame, and being provided with holes fortransverse tubes or rods. Fig. 13 is a perspective view of thesill-casting shown in Fig. 1 for securing the main sills to the tubingof the frame.

On each side of the draw-bars, and equidistant between the draw-bars andthe side sills, I introduce a strong rod (four to each eightwheeled car)passing through the end sill and through the transom, and having ashoulder on each side of the transom to hold the straps which hold thelongitudinal tubes,with screwthreads and nuts on the outer end ofsaidrod. Either in bumping or in suddenly starting the ear thisauxiliary rod relieves the end sill or the transom, as the case may be,and,while not absolutely indispensable, is a si1nple,important, and veryvaluable addition in this construction of ears.

Any of the ordinary draw-bars, draw-bar springs, and followers willanswer my present purpose, and as to the details of construction forsuch a car floor-frame not herein specified the constructions in tubularcars heretoforeA patented and used may be adopted.

Means have heretofore been designed for adding the housing orsuperstructure of a box-car to a tubular floor-frame which are incapableof practical use,while the bracket arrangement herein shown anddescribed constilOO tutes,as I have ascertained by experience,

practical, strong, and safe means by which said superstructure may bereadily attached and detached, even after said floor-frame isconstructed.

I claim- 1. In a tubular ear, a bracket for attaching together thecar-sill and the longitudinal rods or tubes, fitted onto said tubessubstantially as shown and described.

2. The insideV corner casting herein described, constructedsubstantially as shown in Figs. 2 and 3, and having two recesses for thereception of the longitudinal tubes, and also holes for the passage ofrods or bolts through the end and side sills to unite said eastingwithsaid sills and the outside or push 7 castings, substantially as and forthe purpose set forth.
